Those are likely zaps by going to a person's profile and zapping them without selecting any specific note:

(And those kind of zaps do not activate a notification in your nostr client)
You mean profile zaps. I usually see those in Damus too. For a note it usually says : xyz zapped your note and for the profile it’s : xyz zapped your profile or zapped you… I’m not sure what’s going on right now
Oh ok, in Amethyst you don't see the profile zaps. Then I don't know what's up :)
Thanks for helping :)
I’ll figure it out eventually
